For each method or attribute block (to init them), we recursively go into the AST to find each variable declaration in order to give them a fixed position (in the environment).
This is a small recursion since we only need to go deeper for block constructions.

The second commit completely replace the frames of the interpreter to avoid allocation of these hashmaps in the virtual machine, the commit is pretty verbose but this is mainly code from the interpreter.

Now, nitvm take 2.67 seconds, 2.83 for niti: 8% better.

9 years agoMerge: Enable tagging of primitive types
Jean Privat [Wed, 18 Mar 2015 05:41:34 +0000 (12:41 +0700)]
Merge: Enable tagging of primitive types

Another old optimization since it was present in PRM, the Australopithecus compiler.

This PR bring back tagging of the primitives types Int, Bool and Char.

Previously, all primitive types where boxed.
It means that when a Bool, or any primitive object, must be manipulated in a polymorphic way (i.e. as an Object in a `val*`), a small box is allocated that contain the value and the reference (the `val*`) points to the box.
The boxes use the layout of real objects (with a pointer to the class table and everything) so that boxes are compatible with the various implementation of OO mechanism, eg `obj->class->vtf[METHODID]` to implement a method invocation.

Basically boxes work like Java auxiliary classes (eg. `Integer`) except that they are fully transparent for the user and, more important, a implementation detail unrelated to the specification of the language.
Therefore, one can provide a different implementation, like tagging, without worrying about breaking the specification and existing programs.

The principle of tagging is that `val*` values are overloaded to store primitive value in addition to genuine pointers to allocated object.
The two low bits of the `val*` (so 4 combinations) is used to distinguish if the value is a real pointer (in this case, bits are 00) or one of the masqueraded common type (Int, Bool and Char).
If it is a pointer there is nothing to do and the value can be used as is.
If it is a primitive value, then the real value is stored in the remaining bits (but shifted).
The trick works because allocated objects are aligned so that pointer of genuine allocated object have always their last two bits at 00.

The advantage of tagging is that this reduces the cost of manipulating primitive values in a polymorphic way, especially this reduce the numerous allocations of short lived boxes that is slow to do and increase the workload of the GC.
By comparison, with tagging, masquerading a Bool as a `val*` is easily done with few bit-to-bit operations.

Unfortunately, tagging is not a panacea since `val*` is not always a real pointer and require specific and additional protection to avoid doing `obj->class` in the case of `obj` is in fact a tagged value.
Therefore tagging add a minimal but systematic overhead to OO mechanisms like calls, type tests and equality tests.

After quick tests, the numbers are encouraging.

For nitc/nitc/nitc:
before: 0m6.796s
after: 0m6.452s (-5%, not that bad)

Benches where run and tagging was either comparable or better than systematic boxing:

Especially `lib/ai/examples/queens.nit` get the best of it with a -20% improvement.
That make sense because it use arrays of integers to model the states of the n-queen problem. And unfortunately arrays are implemented in a homogeneous way where elements are always polymorphic `val*` values.
Once generics and collections are implemented in an heterogeneous way for primitive types, the benefit of tagging should be reevaluated.

Note: funnily, the main commit of the series, the one that implements tagging, is only made of insertions of lines (no deletion or changes) and it only modifies a single file.

Merge: Derive all the things

This PR is crazy and inspired by https://github.com/privat/nit/pull/1202#discussion_r26359435
Basically, you will find here some hackish user-level pseudo meta-programming with optional unsafe support from the execution engines trough injection of code in the AST.

The idea is a generalization (and a basic simplification) of the approach or @xymus for serialization.
If fact, there is 2 level of generalizations.

In the compiler, a new phase `deriving` offers a static deriving mechanism. For instance, the annotation `auto_inspect` will implements the `inspect` method with a simple recursive inspection of attributes.

In the standard library, a new module `deriving` offers a general mechanism with a new standard `derive_to_map` method that is expected to dump attributes in a simple HashMap.

This basic low-level method is used to provide user-defined deriving methods.
For instance, the module provide basic derived implementation of `==`, `to_s` and `hash` in pure Nit at the user-level.

Moreover, the compiler phase `deriving` is extended to provide `auto_derive` that statically implements `derive_to_map`

Here an example from the code:

~~~nit
class A
   auto_derive
   super DeriveToS
   var an_int: Int
   var a_string: String
end

var a = new A(5, "five")
assert a.to_s == "an_int:5; a_string:five"

Merge: Nitunit works with groups and markdown files

A lot of work but quite straightforward. Nit can be a really nice language when doing maintenance of old code.

The first part ot the PR updates the nitdoc to test documentation of groups (as requested by #1201)
The second part of the PR (I planned to do 2 PR but the second was more easy to do than expected) makes that nitunit can also process sand-alone markdown files (documentation, wiki pages, etc.).

Example:

~~~
-- foo/
   |-- README.md
   `-- foo.nit
~~~

~~~sh
# to test all entities of a module (classes, methods, etc.)
$ nitunit foo/foo.nit
# to test all entities of a group (the group and all its modules)
$ nitunit foo
# to test a given markdown file
$ nitunit foo/README.md

Merge: Noise generators: Perlin and interpolated

Intro the PerlinNoise generator and the underlying (but independent) InterpolatedNoise, with some related services.

The rosetta code Perlin noise example (in 3D) is for comparison to my implementation in `lib/noise.nit` in (2D). We do not get the expected result with this implementation, 0.13691995878400010 vs 0.13691995878400012. It may be an error in the implementation of `Float.to_precision`... this will require further investigation.

The optimized `SequenceRead::rand` is a bonus! it is not used in this PR.

Merge: Abstract attribute

Add the annotation `abstract` on attributes.

It is just a syntactic sugar to define a couple of abstract getter-setters with a shared documentation without an associated slot in the instance so it can be used in interfaces.

~~~nit
interface Foo
var a: Object is abstract
end

class Bar
super Foo
         # A concrete attribute that redefine the abstract one
redef var a
end

class Baz
super Foo
var real_a: Object
         # A pair of concrete methods that redefine the abstract attribute
redef fun a do return real_a
redef fun a=(x) do real_a = x
end
~~~

The visibility rules are unchanged with regard to concrete attributes, so by default the writer is private.

Needed cleaning (and a bugfix) are included in the PR
